1. How does a modern fuel cell work ? 11780118 Yuuya Hirai

2. Principle Anode(+) Cathode ( － ) H+H+ H+H+ OH - + ‐ H 2 O+NaOH H 2 O → H + +OH - H2H2 O2O2 2H + +2e - →H 2 2OH - →H 2 O+1/2O 2 +2e - Water(H 2 O) + Electricity Hydrogen(H 2 ) + Oxygen(O 2 ) Water(H 2 O) + Electricity Hydrogen(H 2 ) + Oxygen(O 2 ) Fuel cell

3. Constitution 2H + +1/2O 2 +2e - H2H2 H2H2 2e - 2H + H2OH2O Oxygen Hydrogen 1/2O 2 H2OH2O 2e - Electrolyte Cathode(+) Anode ( － ) Separator Electrolyte Anode ( － ) Cathode(+) Separator Hydrogen Oxygen Hydrogen(H 2 ) Oxygen(O 2 ) Separator Cooling water Guard Power collection board Electrode Platinum

4. Character Demerit ・ High power generation efficiency ・ Use of exhaust heat. ・ Low pollution ・ Quiet ・ Long-life ・ Hydrogen does not exist naturally. ・ Expense is high. Merit ・ Danger of hydrogen

5. Practical use (1) Fuel cell car Fuel cell mobile phone Fuel cell personal computer

6. Fuel cell LP Gas Electricity Heated water Heated water storage ・ Electricity and heat are generated from LP gas. ・ Hot water is made using heat. Bath Kitchen Practical use (2)

7. Future Solar energy generation Wind-power generation Hydropower generation Hydrogen factory Hydrogen storage tank Hydrogen power station Fuel cell car Fuel cell building Fuel cell house

8. Thank you for your attention.
